Declaration which can be invoked, and may have parameters. Classes and functions are functional declarations.

Note that multiple-parameter lists are not reified at runtime, so if you have a function declaration like this:

Integer add(Integer a)(Integer b) => a + b;

It will only have a single parameter list at runtime (the first), and its return type will be Callable<Integer,[Integer]>.
